I saw a news report about smart phone flashlight apps. It seems that many of them written in China, Russia, and a few other not-so-nice countries require access to info on the phone, that something so simple has no need for. They send your info out to the bad guys.

snoopwall.com has a lot of info on security for your smart phone, especially Android. A very good read.
Install "privacy flashlight" by snoopwall. Available at the Play store.
